Symantec Scan Engine Multiple Vulnerabilities
Revision History
None
Risk Impact
Medium
Remote Access Yes
Local Access No
Authentication Required No
Exploit publicly available No
Overview
Three vulnerabilities have been discovered in the Symantec Scan Engine. Symantec
Scan Engine is a TCP/IP server and programming interface that enables third
parties to incorporate support for Symantec content scanning technologies into
their proprietary applications. This gateway-level product should not be
confused with Symantecç—´ desktop product.
The Symantec Scan Engine fails to properly authenticate web-based user logins.
Anyone with knowledge of the underlying communication mechanism can control the
Scan Engine server.
Symantec Scan Engine uses a static private DSA key for SSL communications. This
key cannot be changed by end users and is easily extracted. This opens the
product to a potential man-in-the-middle attack.
There is a vulnerability in Symantec Scan Engine that allows unauthenticated
remote users to download any file located under the Symantec Scan Engine
installation directory. For instance, the configuration file, the scanning logs,
and the current virus definitions can all be accessed by any remote user using
regular or specially crafted HTTP requests.
